SUPERCONDUCTING FIELD POLE

摘要

Superconducting field poles each include a superconducting coil body formed by spirally winding a superconducting wire material, a ferromagnetic outer magnetic field-deflecting member arranged on an end face of the superconducting coil body at a radially outer side of a rotor, and a ferromagnetic inner magnetic field-deflecting member arranged on an end face of the superconducting coil body at a radially inner side of the rotor.

主权项

1. A plurality of superconducting field poles arranged in a circumferential direction so as to correspond to a plurality of phases of an armature winding in a rotor of a superconducting electrical rotating machine, the rotor being disposed coaxially with a stator in an internal space of the cylindrical stator in which the armature winding of the plurality of phases is arranged in the circumferential direction, each of the superconducting field poles comprising:
a superconducting coil body formed by spirally winding a superconducting wire material; an outer magnetic field-deflecting member more ferromagnetic than the superconducting coil body, the outer magnetic field-deflecting member being arranged on or in the vicinity of an end face of the superconducting coil body at a radially outer side of the rotor; and an inner magnetic field-deflecting member more ferromagnetic than the superconducting coil body, the inner magnetic field-deflecting member being arranged on or in the vicinity of an end face of the superconducting coil body at a radially inner side of the rotor.
